Natural Killer (NK) cells are part of our innate immune system with regulatory and effector functions. Different studies suggest that treatment with intravenous immunoglobulins (IVIg) has an immunomodulatory effect on NK cells. IVIg is a first-line treatment for various autoimmune diseases in particular in chronic inflammatory demyelinating polyneuropathy (CIDP). The lack of predictive markers ...

Natural killer (NK) cells are effector cells of the innate immune system that exert direct cytotoxic functions. Ubiquitously-expressed toll-like receptors (TLRs) have been recognized as one of the major components promoting dendritic cell (DC) maturation, which may induce polarized immune responses beneficial to cancer immunotherapy. TLR-activated NK cells and DCs are prerequisite for robust ac...

Syncope is defined as a sudden temporary loss of consciousness and postural tone that is associated with spontaneous recovery. Vasovagal or neurocardiogenic syncope is a common and usually benign cause of syncope. The mechanism may be cardioinhibitory, vasodepressor, or both. Diagnosis is usually made by a typical patient history with a definite trigger. Although vasovagal syncope is considered...

The 37-year nonmilitary mortality rate for initially healthy aviators was determined in a followup program on the U.S. Navy's "1000 Aviator" cohort. Of the 800 survivors of World War II and the Korean conflict, 95 were found to have died from nonmilitary causes over this followup period. This is markedly less than the 208 that would be expected from a random sample of white American men over a ...

background: human peripheral blood nk cells constitutively express cd56 and cd16 antigens. peripheral blood nk cells seem to be strongly related with decidual nk cells, and may reflect the decidual nk cell functional status. there are varied reports concerning the relationship between nk cell cytotoxicity in women with recurrent spontaneous abortion. objective: to study nk activity in women wit...

in recent years, environmental pollution by coal mining is a long-established human activity affecting all levels of life with various environmental impacts by generating heavy metals. the presence of heavy metals even in trace amount is toxic and detrimental to all living organisms. the coal mine area in bokaro is one of the “toxic hotspot” in india. bacteria have evolved uptake and efflux mec...
